• • Product Information
  • Product Name: Phoenix Children's Astronomical Telescope
  • Product brand: Phoenix
  • Item Number: 30070
  • Product color: Silver
  • Material composition: Aluminum alloy + optical glass 
  • Size: 460×220×110mm(Packaging)
  • Weight: 2kg
  • Packing quantity: 5PCS

Light transmission aperture: 70mm(2.4"
Focal length: 300mm.f/4
Oblique mirror: 90°
The warp and weft table and aluminum tripod
Maximum height: 38cm
The standard 0.965-inch accessories include:
Eyepiece: H6mm, H20mm, 3x Balov lens, 1.5x upright lens

The maximum magnification of this model is 150 times (objective lens focal length/eyepiece focal length * several times the Balov magnification = maximum magnification)

The aperture is the most important indicator for choosing a telescope, and it is directly proportional to the clarity and price.

A. Regarding functions:

This model has a gross weight of approximately 2 kilograms and features a circular island where you can view the moon. Tripod height: 38CM.

B. Regarding configuration:

The focal length is 300mm, the aperture is 70mm, and it is equipped with two eyepieces: H6(for daytime viewing) and H20 (for moon viewing at night). Additionally, it comes with a 3x Barov lens, a 1.5x upright lens, and a moon lens. Moon mirror: As there is a large amount of reflected light interference when observing the full moon, using a moon mirror can eliminate these interferences and make the surface of the moon more clearly visible. When in use, please screw the moon mirror into the thread at the bottom of the eyepiece, and then connect the eyepiece to the zenith mirror.

C. Regarding multiples:

The magnifications of the eyepieces for H6mm and H20mm are: 300/6=50 times, 300/20=15 times. If a 3x Balov mirror is also selected, the magnification will be 50x x 3= 150x and 15x x 3= 45x. When a 1.5x positive image mirror is added, the image is a positive one, and the magnifications are respectively: 50 x 1.5=75 times, 15 x 1.5=22.5 times. That is: minimum magnification: 15 times, maximum magnification: 150 times.

D. Calculation Formula:

Objective lens focal length/eyepiece focal length * several times the Balov ratio = maximum magnification

Objective lens focal length/eyepiece focal length = magnification

E. Installation sequence:

Set up the tripod first. Then install the lens barrel. After the tube is fixed, install the star-finding mirror (for the initial search of the target object) on the tube, and then install the eyepiece (choose one of the two eyepieces). After identifying the large target, then adjust it with different eyepieces. Note: When using it for the first time, you must be patient, patient and patient again! The possibility of astronomy being bad is extremely small, not to mention that we have strictly inspected each telescope before sending them out.

F. Of course, the magnification is not the only factor. It mainly depends on a combination of factors such as the aperture and focal length.

For instance, if the Windows of a house are larger, the light will naturally be better and the view will be clearer. It's the same principle.

When using a 3x Barov lens, install the Barov lens first and then the eyepiece.

(To install a Balov lens, the cover on the device that installs the eyepiece needs to be removed.)"

H. Note: Only one of the two eyepieces (H6mm,H20mm) can be installed at a time.

At the same time, only one of the two magnifying scopes (3x Balov scope and 1.5x upright scope) can be selected.

Of course, the magnification is not the only factor. It mainly depends on a combination of factors such as the aperture and focal length.

For instance, if the Windows of a house are larger, the light will naturally be better and the view will be clearer. It's the same principle.

The overall series of J. Ningbo Phoenix offers excellent value for money and is suitable for beginners in astronomy. It doesn't cost much but allows you to appreciate the mysteries of celestial bodies.
